- IMPROVEMENT IN ckAsEs FoR PACKING METAL SHEETS.

Specification forming part of Letters Patent No. 183,356, dated October17, 1876; application filed October 2, 1876.

To all whom 'it may concern Be it known that I, W. DEwEEs Woon, ofPittsburg, county of Allegheny, State of Pennsylvania, have invented ordiscovered a new and useful Improvement in Gases for Sheet-MetalPackages; and I do hereby declare the following to be a full, clear,concise, and exact description thereof, reference being had to theaccompanying drawing, making a part of this specification, in which-likeletvters indicating like parts- Figure l shows a pile of my improvedpackages, illustrating their positions with reference to each other, andthe door on which they rest when stored or in transita. Fig. 2 is aperspective view of a single package complete. Fig. 3 is a diagram ofone corner of the sheetmetal part of the case unfolded, and nearly orabout its full ordinary size. Fig. 4. shows in perspective the sheet ofFig. 3 bent and folded to receive the pack or bundle. Fig. 5 is asectional view of one edge of the complete package. Fig. 6 is aperspective sectional view of one corner of the complete package 5 andFig. 7 is a reduced diagram of the sheet-iron part of the case, showingthe lines of cut and bend.

In the handling and transportation of sheet metal, and more especiallythe liner qualities, such as Russia sheet'- iron, planished sheetiron,&c.,.great loss results not only from the bending and bruising of thesheets, but more especially from tarnishing and oxidation, caused byhandling or by water, or by moisture in the air. This is a serious evilin shipments by sea, lake, or river, and also on railway-cars, since theroofs of cars on which this class of freight is commonly carried arefrequently leaky, and railway companies now take such sheet metal onlyat owners risk. To guard againstthis loss various means have beenresorted to, such as bundling with straps and outer sheets of aninferior quality, sewin g up the bundle in a canvas covering, and alsoinclosing the bundle in a tight metallic' case. None of these methodshave proved'satisfae` tory.

In making my improved case-say, for a bundle of twenty-four sheetstwenty-eight by fifty-six inches each-I take a sheet, A, of the same oran inferior quality, about five inches longer and wider than the bundle.Each corner of this sheet I cut as indicated more particularly in Fig.3. The side edge a a' is then bent up by a crease along the line m ac,and the end edge by a crease along the line x w', and the corner-piece dis folded along its diagonal, bent around against the end or side andsoldered or riveted, the corner ofthe sheet then being as represented inFig. 4. This is d one at each corner. The sheets B, which constitute thebundle, are then putin the box thus made, as represented in Figs. 5 and6, and a wooden or board cover, D, of the same length and width as thebundle, is then placed on top. This cover should be thick enough tostiften the pack, and also to nail to, say, threefourths of an inch,more or less. The projecting edges c c are then folded down onto thecover D, and secured thereto by nails or screws a, with or without aninterposed packing, c,

of india-rubber, fibrous, or other suitable material, with or withoutluting, such as will make a water-tight `joint. If the cover is made lof two or more boards, their joint or joints are preferably luted, andnecessarily so if a perfectly water-tight case is'desired. Across oralong the outer face of the cover D I fasten two or more wooden ormetallic cleats, s, the upper faces of which are somewhat above thelevel of that face ofthe package. These cleats not only hold, st-ffen,and strengthen the cover, but also (the package then being inverted forstorage or transportation) afford a slightly elevated support for thepackage to rest on.

The packages are then piled one on top of another, as represented inFig. 1.-

With packages thus incased itI will not be necessary, for warehousestorage or for railway shipment, to pack or lute the joints. Thepackage, when thus inverted, has a close sheet-metal top, sides, ends,and corners, so that no water can get in from a leaky roof. The packagesare so far apart, and the lower one is so far from the lloor that nowater can get into any package from below,.and also far enough' apartfor the workmen readily to get hold of them in loading and unloading.

In giving the numbers, measurements, and proportions above specified, Ido not mean to limit myself thereto, since they may be varied atpleasure to a considerable extent without any substantial departure fromthe invention.

For some purposes it will answer `to omite-the folds a c, andfnail theedge folds a c' directly to the edges of the cover D.

I claim herein as my invention- 1. A case for metallic sheets,consisting of sheet A, closed at the corners, and secured to a woodencover, D, Vthe llatter'being provided.

with raised cleats s, substantially as and for the purposes set forth.`

2. A water-tight case for metallic sheets,
